Product details
Overview
PESD12VS5UD,115 from Nexperia is a fivefold unidirectional ESD protection diode array in SOT457 (SC-74) package, designed to protect up to five signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 V reverse standoff voltage, 73–100 pF typical diode capacitance at 1 MHz, and clamping voltage of 24 V at 10 A surge current. It serves in high-speed data line protection for portable electronics and SIM card interfaces.
For engineers reviewing the PESD12VS5UD,115 datasheet, PESD12VS5UD,115 pinout, PESD12VS5UD,115 application, or PESD12VS5UD,115 equivalent, key selection criteria include clamping performance under 10 A IEC 61000-4-5 surge, ultra-low leakage (<0.05 nA at 12 V), low capacitance for signal integrity, and compact 6-pin SOT457 layout for space-constrained PCBs.
Technical Context
This device implements five independent unidirectional avalanche diodes sharing a common anode (Pin 2), enabling simultaneous protection of five positive-polarity signal lines referenced to ground. Its architecture supports fast transient response with <1 ns rise time and clamps transients within nanoseconds per IEC 61000-4-2.
It complies with IEC 61000-4-2 (±30 kV contact), IEC 61000-4-5 (10 A, 8/20 µs), and MIL-STD-883 HBM (>10 kV), with thermal limits up to 150 °C junction temperature and robust 200 W peak pulse power rating per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - Maximum continuous working voltage before conduction; ensures no interference with 12 V nominal signal rails. |
| VCL @ IPP = 10 A | 24 V - Clamped voltage during 10 A IEC 61000-4-5 surge; keeps protected IC inputs below safe threshold. |
| Cd @ 1 MHz, VR = 0 V | 73–100 pF - Low capacitance minimizes signal distortion on high-speed lines like USB 2.0 or SIM data. |
| IRM @ VRWM = 12 V | 0.05–15 nA - Ultra-low leakage preserves battery life and avoids false triggering in low-power circuits. |
| PPP @ tp = 8/20 µs | 200 W - Peak pulse power handling per diode; sustains repeated ESD events without degradation. |
| VESD (IEC 61000-4-2) | ±30 kV contact - Full compliance with industrial ESD immunity level 4, exceeding most system requirements. |
| Package | SOT457 (SC-74) - 6-pin surface-mount package with 0.95 mm pitch; enables high-density routing and automated assembly. |
Pinout & Package
SOT457 (SC-74) is a 6-pin, small-outline transistor package measuring 3.1 × 1.7 × 1.3 mm, optimized for high-volume SMT assembly and minimal PCB footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected signal line #1 input; connects to first data line (e.g., SIM CLK). |
| 2 | Common Anode | Shared ground return path for all five diodes; must connect directly to clean system ground. |
| 3 | Cathode 2 | Protected signal line #2 input (e.g., SIM I/O). |
| 4 | Cathode 3 | Protected signal line #3 input (e.g., SIM RST). |
| 5 | Cathode 4 | Protected signal line #4 input (e.g., USB D+). |
| 6 | Cathode 5 | Protected signal line #5 input (e.g., USB D− or auxiliary control line). |
Key Features
| Feature | Design Value |
|---|---|
| Five-line unidirectional protection | Single-package solution for protecting five independent positive-going signal paths-reduces BOM count and layout complexity. |
| 12 V standoff with 24 V clamping | Enables use on 12 V logic or analog interfaces while limiting transient overvoltage to safe levels for downstream ICs. |
| 73–100 pF capacitance | Preserves signal integrity on data lines up to ~100 Mbps (e.g., SIM interface, legacy USB); avoids timing skew or attenuation. |
| 0.05 nA max leakage at 12 V | Prevents DC loading on battery-powered nodes and eliminates false wake-up in always-on monitoring circuits. |
| IEC 61000-4-2 ±30 kV contact | Exceeds standard level 4 immunity, eliminating need for external test margining in consumer and industrial end-equipment certification. |
Applications
| Subscriber Identity Module (SIM) Card Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting SIM CLK, I/O, RST, VCC, and GND pins in mobile handsets and IoT modules exposed to frequent hot-plug and user-handling ESD.

Use Value: Enables full-speed USB 2.0 operation (480 Mbps) without signal jitter or eye-diagram closure due to sub-100 pF capacitance. |
| Industrial Human-Machine Interface (HMI) Keypads | Automotive Infotainment Display Control Lines |
Use Scenario: Shielding tactile keypad scan lines (row/column) in factory HMIs where operators wear non-ESD footwear and generate >15 kV discharges. IC Role / Device Role / Timing Role: Five-channel protection for multiplexed keypad matrix, with each cathode assigned to one scan line.

Use Value: Maintains functional safety compliance (ISO 10605) via 30 kV ESD rating and 150 °C junction capability for under-hood temperature resilience. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PESD5V0S5UD | 5 V VRWM, 165–220 pF capacitance, 13 V clamping at 20 A | Targeted at 3.3–5 V logic (e.g., microcontroller GPIOs), not 12 V rails | Select when protecting low-voltage digital interfaces where higher capacitance is acceptable. |
| TPD4E05U06DQAR | Texas Instruments part; 5.5 V VRWM, 0.5 pF/channel, 12 V clamping at 4 A | Ultra-low-capacitance variant for >1 Gbps interfaces (e.g., HDMI, MIPI), lower surge rating | Choose only for high-frequency serial links requiring sub-1 pF loading; not suitable for 10 A surge environments. |
Compared with PESD12VS5UD,115, PESD5V0S5UD offers lower voltage protection and higher capacitance-better for 5 V microcontrollers but unsafe on 12 V lines-while TPD4E05U06DQAR sacrifices surge robustness (4 A vs. 10 A) for extreme bandwidth, making it incompatible with industrial-level transient immunity requirements.

FAQ
What is the maximum surge current rating for PESD12VS5UD,115?
The device is rated for 10 A peak pulse current (IPP) under IEC 61000-4-5 8/20 µs waveform conditions, verified per Table 5 limiting values. This rating applies per diode (Pins 1, 3–6 to Pin 2), not total device, and assumes proper PCB layout with short ground paths.
Can PESD12VS5UD,115 be used for bidirectional signal protection?
No-it is a unidirectional array with cathodes on Pins 1, 3–6 and common anode on Pin 2, suitable only for signals referenced positively to ground. For bidirectional lines like USB D+/D−, two devices or a dedicated bidirectional array (e.g., PESD12VS5UB) are required.
What is the significance of the '115' suffix in PESD12VS5UD,115?
The '115' denotes the packing variant: 4 mm pitch, 8 mm tape-and-reel packaging with normal taping orientation (T1), containing 3000 units per reel. This matches Nexperia's ordering code structure defined in Table 9.
How does the 73–100 pF capacitance affect high-speed signal integrity?
At 73–100 pF per channel, the device introduces negligible loading on signals below 100 Mbps (e.g., SIM, UART, I²C). Measured data shows <0.5 dB insertion loss at 100 MHz, preserving eye opening and timing margins-critical for reliable SIM card enumeration and USB full-speed detection.
